Dual Polarization and Bi-Directional Silicon-Photonic Optical Phased Array With Large Scanning Range
We propose a large scanning range silicon optical phased array (OPA), which is polarization multiplexed and bi-directional with only one waveguide grating antenna array.

High-Q microresonators on 4H-silicon-carbide-on-insulator platform for nonlinear photonics
The realization of high-quality (Q) resonators regardless of the underpinning material platforms has been a ceaseless pursuit, because the high-Q resonators provide an extreme environment for confining light to enable observations of many nonlinear ...

Improving the acousto‐optical interaction by an introduction of a planarisation SiO2 layer
This paper introduces a planarisation SiO2 layer into the configuration of ZnO‐silicon‐on‐insulator for constructing an acoustical resonant cavity to enhance the acoustic density on a silicon‐on‐insulator waveguide.

Silicon-on-insulator nanophotonics [PDF]
Nanophotonics promise a dramatic scale reduction compared to contemporary photonic components. This allows the integration of many functions onto a chip. Silicon-on-insulator (SOI) is an ideal material for nanophotonics. It consists of a thin layer of silicon on top of an oxide buffer.

Optimization of photoluminescence from W centers in a silicon-on-insulator. [PDF]
W centers are trigonal defects generated by self-ion implantation in silicon that exhibit photoluminescence at 1.218 µm. We have shown previously that they can be used in waveguide-integrated all-silicon light-emitting diodes (LEDs). Here we optimize the

Highly-Sensitive Unbalanced MZI Gas Sensor Assisted With a Temperature-Reference Ring Resonator
In this paper we study the gas sensing performance of a compact silicon photonics Mach-Zehnder interferometer (MZI) with a coiled sensing arm. A partially exposed sensor was fabricated using deep UV lithography, with a process resolution of 248 nm ...
